experiment 3: flood

 Question: How does the amount of water that flows through a stream table affect erosion + deposition?

Hypothesis: The water deposits a lot more sand.

Materials: Fine sand, rough sand, clay, 3 cups of water, ruler, stream table, beaker.

Procedure:1. mix fine and rough sand with clay; 2. make the sand flat; 3. put the water in the beaker; 4. wait for the results

Observation: the thing was very fast, almost nothing happened, but the water "flooded" the land

       Conclusion: I have to admit,  it wasn't very interesting.
